SweetToof Posted July 12, 2018 Share Posted July 12, 2018 (edited) https://photos.app.goo.gl/f6CSo61bNbfvNxGbA https://photos.app.goo.gl/SZ1sB7VHe28UeZVj7 Ok so I shot a local Steel match last weekend, pretty much Production div. using a gen 4 glock G19 with stock barrel. On 2 separate occasions, different stages, different mags, I got total lock-up of the gun. Bulged cases that won't fully enter the chamber. I drop the mag and bang on gun to get the slide open. Confirm, yep, bulged case. Now to my own fault I *thought* I case gauged every round for the match, didn't do it at home instead did it as I was loading the mags for each stage. Won't do that again, obviously 2 of these slipped by. So I'm like WTF, 1 bulged is going to happen, 2 is cause for concern. Go home, check out my sizing die and what do I find, but a 22LR case the was totally pierced by my decapping pin. It was preventing the empty case from seating completely into the sizing die, resulting in cases that are way too big. No idea how long its been on there. Must have been in with my 9mm brass getting tumbled and I didn't catch it when I placed the case in my press. Pulled it off, reset the die, cases are sized perfectly now. Also, since its steel challenge style rules, my 2 lockups were obviously my slowest runs on the 2 stages they happened during. Put it behind me and still pulled off a Division Win. Can't be the first time this has happened to someone, but I figured the pin would have broke rather than making it all the way through.

Ssanders224 Posted July 12, 2018 Share Posted July 12, 2018 Pics aren't working for me... But if your sizing die was stopping short, then your OAL and crimp should have been affected as well? If its a 1050, then your primer seating depth also. Link to comment Share on other sites More sharing options...

I would not think the crimp OR OAL would be affected from not being sized all the way to the base of the case. It sized about 70% of the case but not down to the bottom. Length of the case is still the same so I would think it would get up into the seating/crimping die just as far. Regardless, I always check the crimp and OAL so if it was slightly off I would have adjusted them to get it back into the desired spec. Link to comment Share on other sites More sharing options...
M1A4ME Posted July 12, 2018 Share Posted July 12, 2018 I broke a decapping pin like that 3 or 4 years ago. Weird stuff happens. I had a 9MM case in a .40 case one time. First thing I though was a "berdan" primed .40 S&W case. Mangled up both of them at the top. Link to comment Share on other sites More sharing options...

If the sizing die was stopping short, and it had not been adjusted in the tool head to do so, then the stroke was not being 100% completed. Which in turn would definitely affect the OAL and crimp.

motosapiens Posted July 12, 2018 Share Posted July 12, 2018 i use lee dies, so the decapping pin generally slips in the collet instead of breaking, but just last week I had a weird stoppage on my 650, very hard to push the handle all the way down. I looked and scratched my head and took out that case from the sizer, next one did the same thing. Finally figured out I had a 9mm hollow-point bullet impaled on my decapping pin. It was apparently inside the first case, and my shoving hard just stuck it onto the decapper where it interfered with the next case too. Link to comment Share on other sites More sharing options...

Wow this is another one of those things you'd never think of until it happens to you. Link to comment Share on other sites More sharing options...

Bkreutz Posted July 13, 2018 Share Posted July 13, 2018 Case gauges are all different, you need to find a case gauge that is tighter than your gun's chamber. One way to find out is when you get a round that won't chamber in your barrel, check your gauge, if it goes in, throw it away, it's useless. I have a hundo "supermatch" which is at SAAMI minimums. They stopped making this because people were complaining about the number of failures. (go figure huh?) What I use it for is when fails the Supermatch, I check it in the chamber, if it passes, it gets used. I'm to the point where I can tell if one is going to pass or fail. The ones that pass the Supermatch don't even get checked a second time. Speeds up my process immensely. Link to comment Share on other sites More sharing options...

Yeah case gauging and then plunking is going to be the new method. Lessons learned with this one Link to comment Share on other sites More sharing options...

I check the factory rounds I carry in a gun this way, I’ve plunked close to 1500 rounds of Gold Dot (357 Sig and 9x19), 500 of Winchester SXT (9x19) and over 500 Hornady XTP (380 Auto) no failures, this has been over 10 years. Tactical Timmy stuff aside, that was an interesting die failure, and one I should look out for, as I collect all brass when cleaning the range, including .22.
